GRUB error 2 on new installation

[cdsJerry]

I have a new machine running RAID5. Nothing on any drives prior to Proxmox installation. The installed completed with no problems then told me to reboot and log in via a web browser. I rebooted the machine but it hangs with "GRUB Loading stage1.5. GRUB loading, please wait... Error 2" on the screen.

This is my first experience with Proxmox.

Machine specs:
8GB DDR3 RAM
500 GB drives in RAID5
Intex Xeon QC X3440 2.53 GHz CPU

Hi,
do you have more than one raid-volume defined with the raidcontroller? Or another hdd in the server?
Perhaps the drive-order isn't right. Proxmox install grub during install to the first disk.
How big is your raid-volume? You can't use volumes > 2TB (but i think it's makes trouble during installation).

Brand new hard drives, 500GB. Totally new installation. The RAID shows up correctly in the BIOS. There have never been partitions made to the drives. It's all one volume. There are no errors during installation, just when it reboots after installation.

raid in bios? what raid controller do you got?

Hello,

I once had such a mistake, because a USB flash drive was plugged in
I would take everything out once.
Even if more drives are plugged in, as a test out plugs ...
With your "correctly in the BIOS" you mean the RAID BIOS?
Or you mean the (fake or SW) RAID in Mainboard BIOS (It never really works for Linux I think).?
And in the Mainboard BIOS what is the first start sequence => the Hardware RAID Controller ?

EDIT:
and if nothing helps, maybe SuperGrub is your friend?

I once had such a mistake, because a USB flash drive was plugged in.
I do have two USB devices plugged in, a keyboard and a mouse. Proxmox puts an arrow on the screen however I'm unable to move it with the mouse (Logitech standard laser mouse).
I would take everything out once.
Even if more drives are plugged in, as a test out plugs ...
So I should disconnect three of the four drives? Will it be able to build the RAID later if I do this?

With your "correctly in the BIOS" you mean the RAID BIOS?
Yes. The BIOS gives me the option of setting the SATA drives as RAID and I've done that. If I press Control-I to enter the RAID controller during bootup I come to an Intel Matrix Storage Manager ROM v8.9.0.1023 PCH-D wRAID5 menu. It shows my four physical disks as being Member Disks with One Volume using RAID 5 (Parity) with 64kb Strip 1.3TB, Normal Status, bootable.
I have five options 1)Create Raid Volume, 2 Delete Raid volume, 3) Reset disks to non-RAID, 4 Recovery volume options and 5) Exit.

Bootup sequence is the DVD drive first, then the RAID controller.

No No.1
with USB devices I only mean devices from which the Mainbord can boot ( keyboard and a mouse I don't know)
No No.2
"more drives" of course not the hard drives of the RAID system;-) (sorry for the misunderstanding)
only if any additional

"Intel Matrix Storage Manager"
I do not know whether that is compatible with Linux (I only use Adaptec or 3Ware or NO! Raid)

Do you have a specific controller you suggest? I'm a small company and $1500 for a controller just to get KVM abilities is probably not in the budget. My needs were KVM and the ability to do a bare metal restore. I may need to re-think Proxmox for my situation.

$1500 for a controller wow! that is also nothing for my little educational institutions and schools

Yes,
what allways run under Linux is 3Ware like
3ware9650SE-4LPML with Battery Backup Unit (BBU) For me I will work with good sata hdd (1TB WD-RE4 or Seagate Constellation maybe) in Raid10 not Raid5. There is a good Web management Tool also for Linux and a CLI Tool

I myself have a Adaptec RAID 3405, it also runs very well for my very small company.
Therefore all I have is similarly, I would like to switch completely to 3Ware.
(The Adaptec so you can cheap get from me (is about 1 years old.) ;-)

For both linux 2.6.* has drivers onboard

Thank you. I went ahead and ordered a 3Ware9650 SE-4LPML unit. Should be here in a couple of days and then I'll attempt this again. How important is the battery backup if the computer is on an UPS? That option seems to add significantly to the cost and if I'm on an UPS, isn't it redundant?

you need both, just think of a faulty power supply or mainboard. in this case a UPS does not help. you should also deactivate the cache on the hard disks, therefore your raid volumes only uses the controller cache, secured with BBU.
